What is the greatest common factor of 21 49 and 63?
To find the greatest common factor (GCF) of 21, 49, and 63, we first need to find the prime factorization of each number. The prime factorization of 21 is 3 x 7, 49 is 7 x 7, and 63 is 3 x 3 x 7. The GCF is the product of the common prime factors raised to the lowest power they appear in all the numbers, which in this case is 7. Therefore, the GCF of 21, 49, and 63 is 7.
What is the HCF of 21 and 49?
The first step when finding an HCF is to break the numbers down into their prime factors. In this case we get: 21 = 3x7 49 = 7x7 The next step is to identify any common prime factors. In this case both numbers have a 7 as a prime factor. There are no more common prime factors, and thus the HCF of 21 and 49 is 7.
